#Hum to search

Google Search has recently launched the new 'Hum to Search' feature, allowing users to search a song by humming, singing a melody, or whistling. To enjoy the feature, users should go to the Google Search widget and tap the mic icon. From there, just say, "What's this song?" or click the "Search a song" button, then start humming for 10-15 seconds. It is also accessible through the Google Assistant by saying, “Hey Google, what’s this song?” and humming the tune afterward. Each song's melody serves as its own identity or "fingerprint." The machine learning models can match tune, whistle, or singing to the right “fingerprint.” After humming a melody into Search, the machine learning models transform the audio into a number-based sequence representing the song’s melody. The models are also trained to identify songs based on various sources, including human singing, whistling, humming, and studio recordings. This feature was made possible by the Google AI Research team’s music recognition technology.
